The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse.
Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. The Raspberry Pi project originally leaned towards the promotion of teaching basic computer science in schools and in developing countries.
All over the world, people use the Raspberry Pi to learn programming skills, build hardware projects, do home automation, implement Kubernetes clusters and Edge computing, and even use them in industrial applications.

superuser do or substitute user do
sudo , which is an acronym for superuser do or substitute user do, is a command that runs an elevated prompt without a need to change your identity. Depending on your settings in the /etc/sudoers file, you can issue single commands as root or as another user.
OR
sudo is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser.
pi@raspberrypi:~ $ sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
network={ ssid="wifiName_1" psk="wifiPassword" }
network={ ssid="wifiName_2" psk="wifiPassword" }
Then click Ctrl+x
Then click Y it will be saved!
Now you can see you have successfully connected into your wifi router
Now Let's Configure Raspberry Pi with the help terminal¶Then Enter
Goto to 3rd option interface Options
Then Click
Now can see Interface option
Then click
Use Arrow button left and right
press select button then Enter
If it will ask you then select YES button then click now your SSH will be enable!
Then press OK
Then now enable all the thing by previous method
Use Arrow button left and right
select finish button then Enter
After the click! It's mean you have configure all interface options
After the setting!
Before starting working first you have to Update or Upgrade your Raspberry OS by this command
First Update then upgrade
1.) sudo apt-get update
2.) sudo apt-get upgrade
type: sudo apt-get update
after the update type: sudo apt-get upgrade
after some second it will ask you Do You Want Continue [Y/N]
type y
Then Enter
Your raspberry pi is update or upgrade successfully
pi@raspberrypi:~ $ sudo reboot
pi@raspberrypi:~ $ sudo poweroff
pi@raspberrypi:~ $ sudo shutdown -h now
pi@raspberrypi:~ $ ls
pi@raspberrypi:~ $ sudo apt-get install nmap
then click y it will start installation
pi@raspberrypi:~ $ nmap -sn 192.168.1.0/24
pi@raspberrypi:~ $ htop
pi@raspberrypi:~ $ hostname -I
pi@raspberrypi:~ $ wget URL
pi@raspberrypi:~ $ cat /proc/version
pi@raspberrypi:~ $ pwd
pi@raspberrypi:~ $ mkdir folder_name
pi@raspberrypi:~ $ rm folder_name
or
pi@raspberrypi:~ $ rmdir folder_name
pi@raspberrypi:~ $ cat *.txt
If you want to sort files based on the file extension like TXT, PDF, etc., you can use the cat command. This command works like a charm on Raspberry Pi.
pi@raspberrypi:~ $ sudo su
On Raspberry Pi, if you get the “Permission denied” output, it means you don’t have the privilege to modify or access that file. In such cases, you can type sudo su and hit enter to get into the elevated permission mode. Now, you can execute the command and won’t face any errors.
Now let's Configure with GUI (Graphical User Interface)¶Click the Raspberry icon
You can control most of your Raspberry Pi’s settings, such as the password, through the Raspberry Pi Configuration application found in Preferences on the menu.
In this tab you can change basic system settings of your Raspberry Pi.
You can link devices and components to your Raspberry Pi using a lot of different types of connections. The Interfaces tab is where you turn these different connections on or off, so that your Raspberry Pi recognises that you’ve linked something to it via a particular type of connection.
Make Sure You desire things!
After the all setting please reboot Raspberry Pi¶Download and Installation Putty¶Step 2: Configuration and Installation¶1. Double-click the downloaded MSI file to start the installation.
2. Click Next on the welcome screen to continue with the installation.
3. Click Next if you don't need to modify the installation path. Click Change... to specify another path.
4. Select which product features you want to install. Click Install.
5. Upon completing the installation, the program shows a 'Setup complete' screen. Check/uncheck the View README file option if you want to see the developer's notes. Click Finish to exit the installer.
A successful PuTTY installation window.
Step 3: Run Putty¶Run PuTTY after the installation to make sure it functions properly.
Double-click the icon on Desktop or search 'putty' in the search bar and press Enter.
How to run PuTTY after installation.
If there were no issues during installation, the PuTTY configuration window opens:
The PuTTY configuration window allows you to specify how you want to connect.
The configuration options allow you to set up the connection type, port, and connect to a server. Choose between SSH, Telnet, SUPDUP, raw, rlogin, serial, or bare SSH connection, and enter a server hostname or IP address.
1) Make sure that SSH is enabled on your Raspberry Pi
2) Find out the IP address of your Raspberry. I usually scan my network with Fing to find the Raspberry. In case you have access to the console you can also type the following command:
find IP by this command
pi@raspberrypi:~ $ sudo ifconfig
it will show the network adapters and the assigned ip-address.
3.) The Putty window opens
If you haven't find IP goto this link and download Advance IPscanner¶https://www.advanced-ip-scanner.com/download/
Downloading will be start automatically¶Click “Open” and you’re ready to log on.¶Standard user = pi --------------------->Defualt User is pi¶Standard password = raspberry ----------->Defualt Password is raspberry¶
You can also view GUI of Raspberry Pi with the help of VNC Viewer¶Connect from Windows client: Visit the RealVNC https://www.realvnc.com/en/connect/download/viewer/ site and download the client for your operating system and install. Once it’s done, fire up the VNC viewer and enter the Raspberry PI IP address and hit enter. You are going to see a warning message like this.¶
After the continue just enter the user or password then click connect now you can see RaspberryPi Screen¶
